ABSTRACT

A system for treating amblyopia through the visual stimulation of the brain through a predetermined regime is provided. The system for treating amblyopia comprises a headmountable visual content display device, a controller unit, a visual content source, a data storage device, a graphic processing unit and an audio source. A protocol useful for treating amblyopia by visual stimulation of the brain is also provided. A predetermined regime useful for treating amblyopia by stimulation of the brain is additionally provided.

BACKGROUND OF THE PRESENT INVENTION

Amblyopia is characterized by poor or indistinct vision in an eye. It is one of the most common children ophthalmic disorders; it affects 1-5% of the population, and is generally associated with a history of strabismus, anisometropia, or deprivation of vision early in life by vision-obstructing disorders such as congenital cataract. Amblyopia is a developmental problem in the brain, not an organic problem in the eye. The part of the brain receiving the visual information from the affected eye is not stimulated properly, and develops abnormally. Blood oxygenation level-dependent (BOLD) functional magnetic resonance imaging (fMRI) is a widely used brain mapping technique, which can be used to evaluate the neural activity in the brain by measuring the blood flow to the local vasculature. More recently, fMRI has enabled the noninvasive investigation of brain cortical function in human amblyopia. It has been found that amblyopia is associated with lesions in the striate cortex (Brodmann area 17) and lateral geniculate nucleus (LGN) (Int J Med Sci 2012, 9 (1), 115-120).

An adult brain also poses some plasticity; however, it is much more limited than in an infant brain. However, there are certain conditions which can facilitate a circuit rewiring in a mature brain. At a cellular and molecular level, the adult plasticity is dynamically limited. Some of these “brakes” are structural, such as perineuronal nets or myelin, which inhibit neurite outgrowth. Others are functional, acting directly upon excitatory-inhibitory balance within local circuits (J. of Neuroscience, 2010, 30 (45), 14964-14971). It is contemplated that the plasticity in the childhood and adulthood may be induced by lifting these brakes through the exposure to a customized video content.

The conventional treatment of amblyopia involves full or part-time patching of the strong eye in order to force the use of the deficient eye. Owing to the risk to the strong eye, full-time patching is rarely employed nowadays. Since the critical period in humans is generally thought to end at 7-8 years of age, it is not surprising that the outcome of occlusion treatment is better in younger children than in those older than 6 years (Invest Ophthalmol Vis Sci. 2004, 45 (9), 3048-54). However, the full-time occlusion has been reported to be successful in children aged 9-14 years (Eye (Loud). 2004, 18 (6), 571-4), and the part-time occlusion (with patching of 2-6 hours per day) in children aged 7-17 years (Arch Ophthalmol. 2005, 123 (4), 437-47); in most children aged 7-12 years, the improvement in acuity persists for at least a year after termination of patching (Arch Ophthalmol. 2007, 125 (5), 655-9). Even patients aged 13-17 years may still respond positively to the part-time patching if they have not been treated previously, although it is not yet known whether their visual acuity improvement is permanent (Arch Ophthalmol. 2005, 123 (4), 437-47). However, the greatest threat to a successful patching treatment of amblyopia in little children is a lack of compliance.

Thus it is strong felt and unmet need to provide an amblyopia treatment through a visual stimulation system and method.

The reference is made to FIG. 3 that schematically illustrates a protocol (200) useful for treating amblyopia by visual stimulation of the brain comprising the following steps:

-   -   i. obtaining a system useful for treating amblyopia (201);     -   ii. streaming a video content and a sound track to a controller         unit (202);     -   iii. modifying presentation of said video content displayed on         at least one displaying area (203);     -   iv. displaying said modified presentation to at least one eye         (204);     -   v. providing an audio stimulation (205).

In some embodiments of the present invention the modifying step is achieved by image processing of the video content according to the predetermined regime. In other embodiments the modifying step comprises altering the display parameters affecting image presentation of at least one displaying area. The audio stimulation is provided to at least one ear.

The Regime

The reference is made to FIG. 4 that schematically illustrates a dynamic predetermined regime (300) useful for treating amblyopia by visual stimulation of the brain comprises:

-   -   i. modifying over at least one time unit presentation of a video         content displayed on at least one displaying area by means         selected from the group consisting of image processing or         changing at least one display parameter (301);     -   ii. inserting at least one overlay of at least one object on the         video content displayed on at least one displaying area (302);     -   iii. introducing at least one flicker event (303);     -   iv. triggering an audio stimulation configured to be         administered to at least one ear configured to be coherently         connected to the appearance of at least one overlay (304);

The regime is configured to modify the display parameters affecting image presentation over at least one time unit in some embodiments of the right and left displays, and in other embodiments of the left and right predefined displaying areas. In one of the embodiments of the present invention the regime is configured to alter the presentation of the video content by implementation of the image processing techniques known in the art. In some embodiments of the present invention at least one time unit is configured to have a duration of less than a second. In other embodiments of the present invention at least one time unit is configured to have a duration of at least one second.

The display parameters affecting image presentation to be modified are brightness, contrast, saturation, sharpness, resolution, or any other parameter known in the art and combinations thereof. Furthermore, the regime is configured to modify the intensity of the display parameters affecting image presentation within the range of −99% to +99% of the intensity of the same parameters of the original streamed video content.

The regime is configured to modify the presented video content in such way that, for example, an enhanced sharp and\or bright video streaming is displayed to the deficient eye during most of the protocol, whereas the dominant eye will be exposed to a dampened i.e. dim image with poor video image quality. Additionally the enhanced video and dampened video streaming is accompanied by an audio stimulation. The audio stimulation can be exemplified in a non-limiting way by the elevated volume administered to the ear which is next to the deficient eye and by the reduced volume administered to the second ear.

Furthermore, the regime may also be configured to insert at least one overlay of at least one object stored as a file at the data storage device over the streamed video content, such that this modified video is displayed to the deficient eye. Additionally the regime is also configured to trigger an audio signal stored as a file at the data storage device that accompanies the appearance of the aforementioned object. This audio stimulation is configured to be administered to the ear positioned at the side of the deficient eye, or alternately the opposite ear. For example in non-limiting way, the controller unit insets the overlay of a bouncing ball and simultaneously the controller unit trigger the audio signal “ball” or elevates the volume of the audio streaming. Moreover, the regime is also configured to introduce at least one flicker event displayed to the deficient eye accompanied by an audio signal such as in non-limiting way by the sound of thunder or another attention focusing sound. The flicker occurs when the brightness is abruptly and momentarily dropped to a minimal value for time intervals sufficiently long to be noticed by a human eye, alternatively, the flicker occurs by displaying a sequence of frames which are not part of the original sequence of frames of the presented video content. The predetermined regime is configured to operate in real time.

Furthermore, a visual stimulation regime for a binocular image display device comprises at least one visibly noticed intensity alteration of at least one image parameter defining a video image presented on at least one display area (by way of clarification, the term “visibly noticed intensity alteration” shall mean alteration of any visual stimulus allied to the brain via the eyes); where the intensity alteration of the image parameter is configured to be in the range of −99% to +99% of the defined video's image parameter, wherein the image parameter is selected from the group consisting of contrast, brightness, sharpness, saturation, resolution etc. and any combination thereof. Additionally this regime comprises at least one visibly noticed intensity alteration of at least one value of at least one image parameter defining a video image presented on at least one display area; where the intensity alteration of the image parameter values is configured to be in the range of −99% to +99% of the defined video's image parameter, wherein the image parameter is selected from the group consisting of contrast, brightness, sharpness, saturation, resolution and any combination thereof.

Moreover, a visual stimulation regime for an image display device comprises at least one visibly noticed intensity alteration of at least one image parameter defining a video image presented on at least one display area; where the intensity alteration of the image parameter is configured to be in the range of −99% to +99% of the defined video's image parameter, wherein the image parameter is selected from the group consisting of contrast, brightness, sharpness, saturation, resolution etc. and any combination thereof. This particular regime additionally comprises at least one visibly noticed intensity alteration of at least one value of at least one image parameter defining a video image presented on at least one display areas; where the intensity alteration of the image parameter values is configured to be the range of −99% to +99% of the defined video's image parameter, wherein the image parameter is selected from the group consisting of contrast, brightness, sharpness, saturation, resolution or any other parameter known in the art and any combination thereof.

It is well accepted that during increased neural activity, the cerebral metabolism rate of glucose (CMRglu) is increased and concurrently, cerebral blood flow (CBF) and cerebral blood volume (CBV) are elevated. For example the relative cerebral metabolic rate of oxygen CMRO₂ in the visual cortex increased significantly during visual stimulation consisted of a circular black and white checkerboard, reversing at 8 Hz and its magnitude change was 0.3-0.7 times the CBF change. A weak positive correlation between CBF in visual cortex and CMRO₂ changes was observed, suggesting that the CMRO₂ increase is proportional to the CBF change (Magnetic Resonance in Medicine 1999 41, 1152-1161).

In other research an elevation of retinal blood flow by the luminance flicker stimulation in humans it has been discovered (Investigative Ophthalmology & Visual Science 2011, 52 (1) 274-277). Furthermore, it was found that changes in the cerebral blood flow in the primary visual cortex were 16%±16% and 68%±20% for the photic flicker stimulation at 2 Hz and 8 Hz, respectively. Whereas the changes in the cerebral blood volume were 10%±13% and 21%±5% for 2-Hz and 8-Hz stimulation, respectively (J Cereb Blood Flow Metab, 2001 21, (5), 608-612). The experiments on cats demonstrated that the optic nerve head (ONH) blood flow and [K⁺] increased during the flicker stimulus (Investigative Ophthalmology & Visual Science 1995 36, (11), 2216-2227). The largest increase in K⁺potential occurred at 30 Hz whereas the largest ONH blood flow increase occurred at 40 Hz.

The regime of the present invention is configured to increase the cerebral blood flow in the brain.

Non-limiting examples of the predetermined regime:

The tables in FIG. 5 to FIG. 12 illustrate the examples of the predetermined regime where the left eye is a deficient eye and a strong eye is the right eye. The term time unit presented in the tables can embody fractions of a second or at least one second.

The FIG. 5 and FIG. 6 illustrate the regime where the brightness, contrast (603) and sharpness (604) of the dichoptic presentation are lowered for the right eye during the entire regime except at the starting point. The brightness (601) and contrast (602) of the video streaming displayed to the deficient eye is enhanced during the regime, while the sharpness (605) is left unchanged. Furthermore, the duration of the time unit of the contrast and brightness alteration presented to the left eye within the range of time units 8-25 is 1/16 of a second (606). Thus the left eye receives visual stimulation at the frequency of 8 Hz. The duration between time units 45 to 50 represent a resting time where the stimulation is minimal or non-existent, to allow the brain a recovery period and is preferably but not necessarily part of the regime.

FIG. 7 and FIG. 8 illustrate the regime where only the brightness of the dichoptic presentation is changed for the left (801) and right (802) eyes. The brightness of the video streaming displayed to the deficient eye is enhanced during most of the regime, while the brightness of the video streaming displayed to the strong eye is lowered during the entire regime except at the starting point.

FIG. 9 and FIG. 10 illustrate the regime where the brightness (902) and contrast (901) of the dichoptic presentation are enhanced only for the left eye. Furthermore, the duration of the time unit of the contrast and brightness alteration presented to the left eye within the range of time units 8-25 is 1/16 of a second (903). Thus the left eye receives visual stimulation at the frequency of 8 Hz.

FIG. 11 and FIG. 12 illustrate the regime where the brightness, contrast (121) and sharpness (120) of the dichoptic presentation are dampened only for the right eye.
